zjhm/z/ fw States REINFORCEMENT Alexander L. Clement, Holyoke, Mass.

Application October 13, 1955, Serial No. 540,258 1 Claim. (Cl. 20-92)and bottom rails of a wood window sash frequently become loose due tothe failure of the connections therebetween. To reinforce theconnection, a novel reinforcing bracket is provided which strengthensand makes the sash rigid.

The novel bracket is formed from sheet metal to have a flat leg forlying against the face of the end portion of the transverse horizontalmember of a sash or the like and a leg for lying against the face of anend portion of the vertical side member thereof with means for securingthe legs to their respective members.

All of the above cited objects, I accomplish by means of such structureand relative arrangement of parts thereof, as will fully appear by aperusal of the description below and by various specific features whichwill be hereinafter set forth.

To these above and other ends and with the foregoing and variousancillary features and advantages and objects of my invention as willbecome more readily apparent as the description proceeds, my inventionconsists in certain features of novelty, and arrangement of parts aswill be hereinafter more particularly pointed out in the claim hereuntoannexed and more fully described and referred to in conjunction with theaccompanying drawings wherein:

Fig. 1 is an isometric view showing the reinforcing bracket of theinvention;

Fig. 2 is an isometric view of the bracket shown in Fig. l, secured tothe corner of a sash or the like; and

Fig. 3 is an elevational view of the sash portion shown in Fig. 2.

Referring to the drawings more in detail, the novel features of theinvention will now be fully described. In describing the invention,reference will be made to a window sash but it will be understood thatthe bracket is adapted for window screens, storm sash, or the like.

A bracket 2, shown in Fig. 1, which embodies the novel features of theinvention, is formed from sheet metal to have a vertical leg 4 and ahorizontal leg 6 disposed in right angular relation.

The leg 4 is located at one end of the horizontal leg 6 which isnecessary, as will appear. Adjacent edges of the legs are joined by acurve 8, as shown, for strength. The leg 4 is provided with a pluralityof openings 10 for screws and a plurality of pointed prongs 12 arestruck up from the leg 6 for impinging the wood of a sash.

As shown in Figs. 2 and 3, the vertical side member of a sash isrepresented by 14 andthe top or bottom aterit:

horizontal or transverse member of said sash is represented by 16. Aportion of a light of glass is represented by 18. The sash, as is usual,is made from wood members.

The outside surfaces of the members 14 and 16 are recessed or formed toreceive the legs 4 and 6 of the bracket in such a way that the outersurfaces of said legs are flush with the surface of said members, asshown.

The prongs 12 of the bracket are driven into the member 16 so that thesaid leg is secured thereto. Screws 20 extend through the openings 10 ofleg 4 of the bracket for securing said leg to the member 14.

Thus, the member 14 is held to the member 16 against outward movementrelative thereto and against longitudinal movement away therefrom.

Reinforcing brackets may be secured to all four corners of a sash or thelike so as to strengthen the sash at its corners, where looseness ofjoints commonly develops.

The reinforcing bracket is easily applied to a window sash or the like,and functions to strengthen the sash where the connections between themembers has become weakened or may be applied to sash as they aremanufactured.

While I have illustrated and described the invention as embodied in aspecific arrangement, I do not intend to be limited to the details shownsince various modifications and structural changes may be made withoutdeparting in any way from the spirit of the invention.

Without further analysis, the foregoing will so fully reveal the gist ofmy invention that others can by applying current knowledge readily adaptit for various applications without omittingfeatures that, from thestandpoint of prior art, fairly constitute essential characteristics ofthe generic or specific aspects of this invention, and therefore, suchadaptations should and are intended to be comprehended within themeaning and range of equivalency of the claim below.

What it is desired to claim and secure by Letters Patent of the UnitedStates is:

A unitary reinforcing bracket for the jointure of the vertical side andhorizontal end members at the corner of a window sash having coplanarouter surfaces and adapted for overlying the horizontal face of thehorizontal member at the end of the sash and the coplanar related facesat the outer sides of said members comprising, a member having anelongated horizontal leg and an elongated vertical leg extending atright angles from said horizontal leg adjacent one end portion of one1ongitudinal side edge thereof, said vertical leg having a transversewidth relatively less than the length of the horizontal leg, and aportion of the inner longitudinal side edge of said vertical legadjacent said one longitudinal edge of the horizontal leg curving intosaid one edge, the face of the horizontal leg being provided with aplurality of sharp prongs struck up therefrom and being adapted foroverlying the horizontal end face of the end member of a sash with saidprongs impinging said member, and the vertical leg adapted to overliethe coplanar related faces of the horizontal and vertical members and.being provided with openings for screws extending into said members.
